When selecting bearings for your application, two of the most common options are deep groove ball bearings and angular contact ball bearings. While they may look similar, they have different design characteristics and are suitable for different applications. This guide helps you understand the difference between them.
Deep groove ball bearings have a simple, continuous groove in both the inner and outer race. The balls are seated deep in the groove, allowing them to handle radial loads effectively. The design is simple, economical, and requires minimal maintenance.
Angular contact ball bearings have raceways where the inner and outer rings are displaced relative to each other. This design allows them to handle both radial loads and significant axial (thrust) loads at the same time. The contact angle can vary – common angles are 15°, 25°, and 40°.
| Type | Radial Load | Axial Load | Combined Load |
|---|---|---|---|
| Deep Groove | Excellent | Moderate (both directions) | Primarily radial |
| Angular Contact | Good | High (one direction) | Excellent |
Deep groove ball bearings are best for applications where the primary load is radial. They can handle moderate axial loads from both directions.
Angular contact ball bearings are designed to handle combined radial and axial loads. The larger the contact angle, the higher the axial load capacity.
Both bearing types can operate at high speeds. However, due to their simpler design and lower friction, deep groove ball bearings can often handle slightly higher maximum speeds than angular contact bearings of the same size.

Choose deep groove ball bearings when:
The main load is radial
You need an economical solution
High speed operation is required
Axial loads are relatively light
Choose angular contact ball bearings when:
You have significant axial loads in addition to radial loads
Rigid axial positioning is required
Higher thrust capacity is needed
